Non-Custodial Key Management
for DeFi

Smart contract wallets carry execution risks. MPC threshold signing eliminates the single point of failure in key management — without requiring users to manage seed phrases.

Pain Points

The challenges your team faces.

⚠️

Smart contract wallet risks

Account abstraction and smart contract wallets introduce execution layer vulnerabilities. A bug in the contract is a bug in the custody model — affecting all users.

🔑

Seed phrase UX kills adoption

Requiring users to manage 12-24 word seed phrases creates friction and support overhead. Most DeFi users have experienced seed phrase loss or theft.

🏗️

Single point of failure in key management

Browser extension wallets, hot wallet signers, and centralized key stores all create single points of failure — unacceptable for institutional DeFi flows.

🔗

Cross-chain key management complexity

Different signing schemes (ECDSA on EVM, EdDSA on Solana/TON, Schnorr on Bitcoin) require separate key management for each ecosystem.

Solution

MPC threshold signing
for institutional DeFi.

🔐

MPC 2-of-3 Threshold

No single private key ever exists in one place. Signing requires 2 of 3 parties — eliminates any single point of failure at the cryptographic level.

🎯

Policy-based signing rules

Define allowed contracts, spending limits, and chain restrictions per wallet. Agents and users can only execute what policy explicitly permits.

🔗

All signing schemes

ECDSA (EVM), EdDSA (Solana, TON, NEAR), Schnorr (Bitcoin). One MPC framework covers all major chain ecosystems.

⚡

API-native integration

Connect your dApp or DeFi protocol to MPC wallets via REST. Users get non-custodial security without managing seed phrases themselves.
